Getting Javascript to work with my page?

I have an ASP.NET Page

I have placed the following script in my head:

  <script type="text/javascript">
    function getElement(aID)
        return (document.getElementById) ?
            document.getElementById(aID) : document.all[aID];

    function getIFrameDocument(aID){
        var rv = null;
        var frame=getElement(aID);
        // if contentDocument exists, W3C compliant (e.g. Mozilla)

        if (frame.contentDocument)
            rv = frame.contentDocument;
        else // bad IE  ;)

            rv = document.frames[aID].document;
        return rv;

    function adjusticustomers()
        var frame = getElement("icustomers");
        var frameDoc = getIFrameDocument("icustomers");
        frame.height = frameDoc.body.offsetHeight;

and then within my page:

<iframe id="icustomers" onload='adjusticustomers();' runat="server" src="..."> </iframe>

But I am getting the following error:

Creator.master(85,0): error BC30456: 'adjusticustomers' is not a member of 'ASP.creator_master'.
Creator.master(85,0): error BC30037: Character is not valid.

Any ideas on how I resolve this?

Since you have made it run at server it will consider onload as server side function.

Instead of that make it like

<iframe id="icustomers" runat="server" src="..."> </iframe>

and in the Page_Load on the server side

You put 'runat="server" inside the ifram tag. I suppose that will not work. It should be either client side (use the javascript) or server side (use .net code).

I'm getting an error message (javascript side) which is saying the icustomers is undefined.

I am using IE7

So it means your code not able to get the icustomers frame

Anyway to figure out why? All pages are contained within the same directory. As you can see my ID for the page

<iframe id="icustomers" onload='adjusticustomers();' runat="server" src="..."> </iframe>

does match up with


So i am wondering what the potential reasons for the JavaScript not working might be.
